Many a Brave Knight Will Die: Riot's League of Legends MMO Is 'the Grail' - But 2XKO's Demise Has Fans Bracing for Impact

Marc Merrill, Riot Games co-founder, just compared the company's long-gestating League of Legends MMO to the Holy Grail. A quest so noble that "many a brave knight are going to die" pursuing it, he said with characteristic swagger. It is a mythic framing from a man who still believes in Riot's most ambitious project.

But here is the problem: he said it days after Riot announced it is ending active development on 2XKO, a game that launched less than a year ago. The contrast between Merrill's Grail rhetoric and Riot's very recent, very public willingness to walk away from ambitious projects creates an uncomfortable tension. One that fans are already calling out.

"It's the Grail, So Let's Go", What Merrill Actually Said

Merrill appeared at PAX West 2026 in a session titled "Storytime w/ Marc Merrill" alongside Kinda Funny's Greg Miller. The roughly hour-long conversation covered Riot's history, its philosophy, and eventually, the project that has haunted the company's future for years: the League of Legends MMO.

For the first time in a long while, Merrill offered something substantive. The MMO is still in active development. Internally, the team calls it "the Grail."

"We know what players' hopes and dreams are," Merrill said. "We jokingly call it the Grail internally because we're like, f*ck it, many a brave knight are going to die on the Grail quest. But f*ck it, it's the Grail, so let's go."

The framing is equal parts ambition and self-awareness. Merrill knows the history of MMO development is littered with corpses. He acknowledged as much by borrowing the language of Arthurian legend, where most knights who seek the Grail never find it. Some do not survive the search at all.

He framed execution as the make-or-break factor. "Can we exceed in the execution?" Merrill asked, before claiming "the future is incredibly bright" while admitting the mindset is "hard to do at scale."

This is the most substantive public update on the MMO in years. No title. No release window. Just a vibe and a warning.

The 2XKO Elephant in the Room

Days before Merrill took the stage at PAX West, Riot announced on Aug 20, 2026 that it is ending active development of 2XKO in December 2026. The servers stay online. All gameplay content unlocks in September. But the tag-fighter, which launched less than a year ago, is being wound down.

According to Riot's official announcement, the decision stems from running costs that "substantially exceed revenue" and flat player engagement despite regular updates. Notably, core tag-fighter fans responded positively to the game's mechanics and presentation. The studio did not cite quality concerns in its announcement, though the flat engagement figures suggest retention challenges that could point to broader issues beyond pure economics.

The wind-down is not a full shutdown, and precision matters here. "Active development ending" is not the same as "the game is dead." But for all practical purposes, Riot is walking away from a game it launched less than a year prior.

This is the immediate context that makes Merrill's Grail talk land with a thud for many fans. You cannot tell players you are willing to die on a quest when you just demonstrated you will abandon a shipped game the moment the numbers stop working.

Five Years of Turbulence, The MMO's Rocky Road

The League of Legends MMO was announced in 2020. Six years later, it still has no official title and no release window. In between, the project lost its producer, Greg Street, who departed saying the game was "in good hands." The reassurance did little to calm nerves at the time.

The project has reportedly undergone significant internal restructuring, including a reboot that was first reported by Bloomberg's Jason Schreier in 2024, citing sources familiar with the development. A common but worrying sign in MMO development, where resetting progress often means years of work discarded in pursuit of a new vision.

Merrill's remarks are the first substantive public update in a long while. That cuts both ways. It is reassuring that the project is alive. But it is also a reminder of how little Riot has shared over half a decade.

The MMO genre itself is a graveyard of ambitious projects. Merrill's own metaphor acknowledges the risk. The Grail is not guaranteed. Most knights who seek it fail.

Fan Reaction, "Hope This Time You Don't Cancel It"

The skepticism in the community is palpable. Comments responding to Merrill's remarks, highlighted in GamesRadar's coverage of the PAX West session, include the pointed: "Hope this time you don't cancel it."

The sentiment reflects eroded confidence in Riot's ability to see long-gestating projects through. 2XKO's wind-down is the freshest wound, but it is part of a broader pattern. Riot has a history of canceling or restructuring projects that do not meet its internal bar, regardless of how much time and money has been invested. The company's 2024 shutdown of its publishing arm Riot Forge, which produced single-player games in the League universe, remains a recent example of Riot trimming ambitions outside its core live-service model.

The tension is hard to miss. Merrill is asking fans to believe in a six-year-old project with no title, no date, and a history of internal turbulence. Meanwhile, the company just demonstrated it will pull the plug on a shipped game for financial reasons.

There is a counterpoint worth acknowledging. Some fans remain hopeful, noting that Riot's willingness to kill 2XKO might actually be a sign of discipline. If the MMO is not meeting its bar, Riot will kill it too. That is either reassuring or terrifying, depending on your perspective.

What Would "Success" Even Look Like?

Merrill says Riot knows what players hope for. But the MMO space has changed dramatically since 2020. The bar is brutal. World of Warcraft's shadow looms over every challenger. Final Fantasy XIV's redemption arc proved that a live-service game can rise from the ashes, but it also demonstrated the enormous resources required to do so.

The recent landscape offers little comfort. New World launched to strong initial sales before its population cratered within months. Lost Ark found an audience but struggled to sustain it in Western markets. Even Amazon Games, with its considerable resources, has yet to deliver a long-term MMO success. The genre has shifted toward live-service models that blur the line between MMO and other multiplayer genres, and player expectations for constant content updates have only intensified.

Riot's own track record with genre expansion is mixed. Arcane was a triumph, a masterpiece of adaptation that expanded the League of Legends universe in ways no one expected. But 2XKO's wind-down shows that even a beloved IP does not guarantee commercial success. The fighting game space, like the MMO space, demands sustained investment and a dedicated player base that is hard to build and harder to keep.

The "Grail" framing is apt in another way. The Holy Grail is, by definition, something that may never be found. It is a destination that exists only in the seeking. Merrill's own metaphor contains the possibility of failure within it.

Can Riot execute at the scale required? Can a company that just walked away from a game it shipped less than a year ago sustain the multi-year commitment an MMO demands? The Grail quest continues, but the knights are nervous.

And given recent history, who can blame them? The Grail may be worth dying for. But Riot just showed it is not above letting its own knights fall.
